The 3399 and 3395 sensors made by Infineon are two sensors that use MEMS technology, and are known for their acceleration and pressure detection, respectively.The 3399, an acceleration sensor that was introduced early on, is mainly used in areas such as the Internet of Things (IoT), the military, and robotics, and is notable for its high sensitivity, which allows it to capture small changes in acceleration. In contrast, the 3395 sensor is a pressure sensor widely used in scenarios such as automotive manufacturing (e.g., tire pressure monitoring) and medical (e.g., blood pressure monitors), and one of its major strengths is its ability to monitor high pressure changes in real time.
In terms of application scenarios, the 3399 has a relatively narrow range of applications and is suitable for areas that require high-sensitivity acceleration measurements, such as drone navigation or smart homes. The 3395, on the other hand, has a wider range of applications and can fulfill the needs of pressure monitoring in industries such as automotive and medical. Which sensor to choose depends largely on the specific application environment. If you are sensitive to changes in acceleration, the 3399 may be a better choice; if you need to deal with high-pressure changes, the 3395 is the preferred choice.
In summary, the 3399 and 3395 sensors each have their own strengths, and the choice needs to be based on the actual requirements to achieve the best performance. In areas such as IoT and robotics, the high sensitivity of the 3399 will be key, while in automotive manufacturing and the medical industry, the 3395's pressure monitoring capabilities will be indispensable.
